Just at that moment the watchman on the north cried a train. We left the fire and made a breathless race of the six hundred yards downhill to our old position. Round the bend, whistling its loudest, came the train, a splendid two-engined thing of twelve passenger coaches, travelling at top speed on the favouring grade. I touched off under the first driving wheel of the first locomotive, and the explosion was terrific. The ground spouted blackly into my face, and I was sent spinning, to sit up with the shirt torn to my shoulder and the blood dripping from long, ragged scratches on my left arm. Between my knees lay the exploder, crushed under a twisted sheet of sooty iron. In front of me was the scalded and smoking upper half of a man. When I peered through the dust and steam of the explosion the whole boiler of the first engine seemed to be missing.
